You still have belt losses but an alternator can add cheap braking regen to a series wound setup.
Perpetual no, charging 12v battery yes.

Even in a hybrid like mine, regenerative braking makes up for just a small portion of electic use.
The 12V system drains some 150 to 200 Watt constantly so it would eat the power generated by one long braking session (say 15 seconds at 10 kW) within a quarter of an hour. If I hadn't used it up by accelerating away again.
A regular car alternator can generate way less than that.
At 500 Watt 15 seconds would yield just 7500 Joule, just enough to power a 150 Watt system for 50 seconds.
I bet the belt drag alone would annihilate that gain in most situations.
